FOR IMMEDIATE RELEASE

Chubb Estimates Second Quarter Catastrophe Losses

WARREN, New Jersey, July 9, 2013 — The Chubb Corporation [NYSE:CB] announced today that it estimates the impact in the second quarter of 2013 of losses from catastrophes to be approximately $240 million before tax, or $156 million after tax ($0.60 per share after tax). Approximately $175 million of the losses before tax represents Chubb’s estimate for losses from catastrophes in the United States, primarily from various severe storms in the central states. Losses from catastrophes outside the United States amounted to approximately $65 million before tax, most of which were from storms and flooding in southern Alberta, Canada.

Chubb expects to announce its second quarter 2013 financial results as scheduled on Thursday, July 25, 2013 after the close of the market. The press release and financial supplement will be available shortly thereafter on Chubb’s website at www.chubb.com.

Actual results may differ materially from those suggested by the forward-looking statements as a result of risks and uncertainties, which include, among others, those discussed or identified from time to time in our public filings with the Securities and Exchange Commission.
